Patented Dec. 31, 1929 UNITED STATES PATENT OFFICE CHARLES HEUZE, OF AUVELAIS, BELGIUM GRINDING TABLE Application filed June 16,

of the parts of which it is composed, as will be hereinafter described and claimed.

Referring to the accompanying drawings in which corresponding parts are designated by corresponding marks of reference Figure 1 is an end view of a unit mounted on a track-way and showing one embodiment of this invention.

Figure 2 is a plan view of the adjacent ends of the two tables according to this invention.

Figure 3 is a vertical cross section of the vertical aligning means of the pin a and the slot 64*".

A table A is shown in Fig. 1, such table having the usual glass receiving surface a and having longitudinal runners at projecting downwardly from its lower face adjacent to each side thereof. These runners are supported on tracks B having depressed runways I), b. As shown. one of these runways b is adapted to fit snugly the sides of the corresponding runner, and this serves to laterally guide the table. If desired, the width of r this runway may be adjustable, as by an adjustable side member 6 to take up for lateral wear. The opposite track has its runway Z) of greater width than the runner a resting thereon and serves only to support the corresponding side of the table.

For the purpose of holding the adjacent ends of adjacent tables in alignment, one end of each table has projecting from the vertical face thereof, near the side on which is the runway b, (and preferably over the runner corresponding thereto)" a conical pin a which, when two tables are assembled together, enters a corresponding conical recess a in the opposite end of the adjacent table and fits snugly therein. Such pin and recess erally aligned 1928. Serial No. 285,980.

thus serve to align, both vertically and-laterally, the adjacent tables.

From the same end of the table and on the side thereof opposite the conical pin, projects a pyramidal pin a adapted to'enter an elongated slot (1 in the opposite end ofthe adjacent table and to fit snugly therein against the upper and lower walls of said recess of but loosely laterally. vHence such pin a and slot a merely serve for vertically aligning the surface ofthe'tables.

It will be seen that by the construction describedthe tables, while verticallysupported on each side, are guided laterally only from the sideat which is located the snug fitting runway 12; that the adjacent tables, while aligned vertically at both sides, areonly-la'ton one side, andthat the lateral guiding of the tables andtheir lateral aligning is on the same side.

By this construction the assemblage of the tables is facilitated, in spite of expansion of the same under variations in temperature, and accurate registration thereof is provided with the result that the runners a=of the'sev- 7 eral tables working in the lateral guiding runway b are brought and maintained in alignment,'thus reducing the'resist-ance tothe feed of the tables on the tracks.

It will be understood that the several tables, while assembled in a train, may be held together by any of the many well known devices used in the art for that purpose.

Having thus described my invention what I claim is 1. A grinding table having at one end thereof pins located near opposite sides thereof and having on its opposite end a recess of'the same size and shape as one of said pins, and a recess of greater width than the'width of the other pin, said recess being located on the respectively corresponding sides of the end of said table as said pins.

2. A grinding table having at one end thereof a conical pin located near one side thereof and a pyramidal pin'near the opposite side thereof, and having in its opposite end a conical recess of the same size .and shape as the conical pin and a laterally elongated recess, both recesses being in line with the pins in the first named edge.

3. The combination with a track having two runways, of a grinding table having at one end thereof pins located near opposite sides thereof and having on its opposite end a recess of the same shape and size as one of said pins, a recess laterally extended with respect to the width of the other pin on the respectively corresponding sides of its first named end, and two runners located below said pins and recesses on the bottom of the table, the one located below the elongated slot fitting loosely in one of the runways and the other fitting snugly within the other runway.

4. The combination with a track having two runways, of a grinding table having at one end thereof a conical pin located near one edge thereof and a pyramidal pin near the opposite edge thereof, and having on its opposite end a conical recess of the same size as said conical pin and a laterally elongated recess in line with the other pin in the first named edge with runners located below said corresponding pins and recesses, the runner located below the elongated slot fitting loosely in one of the runways and the other fitting snugly within the other runway.

5. The combination of a plurality of grinding tables assembled in a train, each table having at one end thereof pins located near opposite sides thereof and having on its opposite end a recess of the same shape as the pin and a slot laterally extended in respect to the pin on the respectively corresponding sides of its first named end, and means for supporting both sides of the train and for laterally guiding only that side thereof near which are located the recesses.

6. The combination of a plurality of grinding tables assembled in a train, each grinding table having at one end thereof, a conical pin located near one edge thereof and a pyramidal pin near the opposite edge thereof, and having on its opposite end a conical recess and a laterally elongated slot in line with the pins on the first named edge, and means for supporting both sides of the train and for laterally guiding only that side thereof near which are located the recesses.

7. The combination in a grinding train consisting of a plurality ofseparate tables, of means for supporting the train near both edges thereof, and for laterally guiding the train adjacent to one edge only thereof, means located adjacent to each side of the tables for vertically aligning the same, and means for laterally aligning the adjacent tables near one side only, the said means for laterally guiding the train and laterally aligning the tables being adjacent.

In testimony whereof I hereunto affix my signature.
